y VEHICLE-WHEEL.

To all lwhom t may concern:

Be it known'that I, GEORGE W. DAGUE, a citizen of the United States, residing at Alexandria, in the parish of Rapides Vand State of Louisiana, have invented certain new and useful Improvements in Vehiclelheels; and I do hereby declare the tpllowing to be a-full, clear, ,and exact description of the invention, such as will enable othersskilled in thel art to which it appertains to Amake and use the same.V

The Y present invention relates to'V vehicle wheels, and aims lto provide a wheel, which instead of using a pneumatictire employs pneumatic means of novel and improved construction within theA wheel proper to accomplish the cushioning or resilient action, without the objections incident'topneumatic tires which wear out and become punctured easily, whereas they present construction will have a long life.A

A further object of the invention isvthe provision of a vehicle wheel having Yspoke constructions of novelform to provide for the yielding motion between the rim and hub, using air cushions for that purpose.

A still further object isthe provision of such a wheel comprising a novel assemblage of the component elements, in order that the ation. e

' With the foregoing and other ob]ects in view, which will beapparent as the description proceeds, the invention resides in the construction and arrangement of parts-hereinafter described and claimed, it being understood that changes canV bey madei within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure'l 1s a side elevation of the improved wheel.

Fig. 2 is a radial section through one spoke.

The wheel'v includes a suitable rim 1 on` which a tire 2 of solid` rubber or other material is fitted, and said krim surrounds and is spaced from affelly or band 3. The hub l is provided thereon with va chamber 5 to which are attached' in any suitable manner the inner ends .of tubularspokes 6 which have their outer ends suitably secured to the felly or band .3, thus providing the wheel proper. Any suitable number of spokes can be used, although four are shown.

tached. lopposite outstanding pins or' studs S which'project-.through and work within opposite longitudinal slots 9 in the corresponding lspoke 6'. The plunger 7 closes the slots 9, to prevent the escape of air therethrough, and toalso exclude dust and Vforeign matter from the interior spokes. Links 11 are pivotally. connected atV their 'inner ends to the studs 8,- and at their outer ends V.to pieces 10 secured to the inner periphery of theV rim 1, said links 11 being arranged in pairs and extending slidably across the opposite edges'of the ,telly or band 3', thus maintaining the elly and rim in a com- 'mon plane, and permitting them to move relatively in said plane. Said-links serve as guide bars vfor the felly 3 in its movement" toward and away. from the rim, and said links' permit of slight relative angular movement of the rim and felly. e

The relative motion ofthe rim and felly result inthe sliding-movement of the plungers 7' within the spokes 6, and air cushions are v'provided withinsaid spokes .to rev sist ythe displacement of ,the rim and felly,

and to'abso'rbV shocks. j Radial tubes 12 are 'l YsecuredtoV v`thel chamber 5' rand project outwardly axially ,withinthe s okes 6, and the inner ends oftheplungers l are slidable on said tubesf12. '.Diaphragms 13 of rubber.v

crfother elastic material are arranged within the spokes 6 beyond the inner ends of the plungers 7, and are attached to said plungers and tubes. "Thus, the outer edge ofeach diaphragm .13 has a bead lsecured within an annular seat 171with which'the plunger* 7k is provided, Vand the inner edge of the diaphragm has asimilar bead 14 fitted within a seat 15 secured on the tube 12 beyond the ,inner end of the plunger.

rlhe inner end of the plunger has openings 18 within the seat .17, permitting the vflow of air into and out of the chamber'rwithin the diaphragm.

The hub chamber 5V has a nipple '19, siinilar tothe valve stem of'a pneumatic tire, i Y,

for thepurpose of pumping in air, toinflate the diaphragms 15. Thus, by pumping air Vvinto the chamber 5, the air passes outwardly through thetube 12-into the plungers 7 and v thence through the openings 18 into 'the diaphragm chambers. `In this way, the desired air pressure can be maintained within the air cushions of the spokes, similar tothe chamber.

Iiniiation of pneumatic tire. This providesl for the cushioning action of the Wheel, similar to pneumatic tire Wheehit being noted that when the rim and felly move toward one another at the bottom of the Wheel, the linlrs 11 move the plunger T inwardly Within the respective Vspoke 6, Vand the inner edge of the diaphragm istheret'ore moved toward the outer edge, whereby to have aftendenoy to reduce the column of lthe diaphragm greater compression, to resist' and cushion the -motion'betWeen the rim and telly, and it will be noted that the diaphragm i3v can stretch in addition to the yielding action of the Jair. This affords an air cushion that Will provide for easy riding. The tendenc)T for the air to expand in each of 'the spokes Will hold the rim and ifelljiv concentric when vrelieved of strains, end itfsvill also be noted Ythat the air is coniined Within the outer and Vcure a piston 23 tothe end ot the tube l2 to Work Within the plunger 7, so that'the air will be compressed betiveen the piston 23 and outer end o1 the plunger, and it will be noted that t ie outward movement of the plunger will compress the air Within the diaphragm 13. This piston 23 is secured vin place by an apertured nieniberr secured uv'ithinv the end of 'the tube i2.

Having thus described the invention,
